SAFETY DEVICE FOR DOORS AND LOCKS.

Specification of Letters Patent.

Patented May 15, 1906.

Application filed January 15, 1906. Serial No. 296,032. I

T0 at whom, it may concern:

Be it known that I, HARRY S. BRIOKELL, a resident of Pittsburg, in thecounty of Allegheny and State of Pennsylvania, have invented a new anduseful Improvement in Safety Devices for Doors and Locks; and I dohereby declare the following to be a full, clear, and exact descriptionthereof.

My invention relates to safety devices for doors and locks. I

The object of my invention is to provide a cheap, simple, and efficientdevice for attaching to doors which will not only hold the door intactand in place in any tampering with the same or with the lock thereof,butwill also hold said door inplace and prevent the bolt of the lookfrom being interfered with or from being turned back in any suchtampering with said door or look.

A further object of my invention is to, provide a further attachment onthe device which will prevent the key of the look from being turned.

Z My invention consists, generally stated, in the novel arrangement,construction, and combination of parts, as hereinafter more specificallyset forth and described, and particularly pointed out in the claims. j

To enable others skilled in the art to which my invention appertains toconstruct and use my im roved safety device for doors and looks, I wi 1describe the same more fully, referring to the accompanying drawings, inwhich- Figure 1 is a cross-section of a door and frame, showing myinvention applied thereto. Fig. 2 is a longitudinal section of thedevice. Fig. 3 is an enlarged front elevation of the clamping-plate andbar. Fig. 4 is a side elevation of the clamping-plate and bar. Fig. 5 isa side elevation ofa portion of the door and frame, showing the devicefor holding the key from turning. Fig. 6 is a detail view showinganother manner of attaching the bar to the frame.

Like symbols of reference herein indicate like parts in each of thefigures of the drawings.

As illustrated in the drawings, A represents the usual or ordinary door,,which is secured at one side (not shown) to the'usual doorframe B andwhen in its closed position rests against the jamb b on said frame.Within the door A and at one side thereof is the usual lock C, which isprovided with the knob c for operating the holding-bolt c and with thekey D, which fits within the keyhole d for operating thelocking-bolt d,as in ordinary cases. A keeper E is secured in the usual manner withinthe door-frame B, and such keeper is rovided with the usual opening athrough t e same to admit the bolt 0 into the same and into the space orchamber e, formed in frame B in the rear of said keeper.

The safety device F is formed generally of a bar 1 and clamping-piece 2,and such bar is formed of a thin flat piece of metal, so that it can fitbetween the door A and frame B at its inner end portion, which isprovided with the lug or projection 1, extending or bent out at rightangles om the end thereof and fitting within the opening 6 of the keeperE and within the chamber 6 in the rear of said keeper. The outer endportion of the bar 1 extends beyond the face of the door A for thereception of the clamping-piece 2, which is of substantially a U shapeto form a raised portion 2 to fit around and inclose the outer end orprotruding portion of the keep er E. Such plate is formed from a thinfiat piece of metal, so that-said raised portion can be bent therein- Anopening 2 is formed in the end of the raised or reinforced portion 2 ofsaid clamping-piece 2 for fitting over and around the bar 1 to hold theclamping-piece 2 in place and to permit said iece to slide along saidbar, while tooth 3 is ormed in said piece and on one side of saidopening to engage with the ratchet-face 3, formed on the side of saidbar. A leaf-spring 4 is secured at one end to the one side of thereinforced portion 2 of said clamping-piece 2, and its opposite endbears against the opposite side of the bar 1 from the ratchet-faceS. Ahook or fingerpiece 5 is carried by the clam ing-piece 2 and acts tosecure the spring4 t ereto by means of a bolt or rivet 5 thereon, whichpasses through the side of the reinforced portion 2 on said piece.

The use and operation of my improved safety device for doors and locksis as follows:

The end portion of the bar' 1 containing the lug 1 is placed along theframe B and the said lug within the opening 6 of the keeper E and withinthe chamber e, and after this is done the door A can be closed toposition within the frame B andagainst the jamb b and bar 1,which willallow the bolt 0 to rest against said bar and within a seat orrecess 1,formed in said bar. The clamping-piece 2 can now be placed upon the bar1 by inserting the outer end of the said bar within the opening 2 of thesaid piece, when said piece can be slid along said bar to positionagainst the face of the door A and frame B, while the tooth 3 on saidpiece will be held in engagement with the ratchet-face 3 on the bar 1 bythe spring 4. When it is desired to remove the safety device F from thedoor A and frame B, all that is necessary is to grasp the finger-piece 5and by pulling out on the same will cause the spring 4 to becomeslightly relieved of its compression, so that the tooth 3 on theclampingpiece 2 will be disengaged sufficiently from the ratchet-face 3on the bar Land so allow the piece 2 to be slid along and off the bar 1.When this is accomplished, the door A can be opened and the bar 1grasped to remove said bar from the frame B through the lifting of thelug 1 on said bar from the chamber 0 and opening 0 in the keeper E. Whenmy improved safety device for doors and locks is in use and it isdesired to prevent the turning or. removal of the key D in the unlockingof the bolt 61, a rod 6 can be employed and be provided with a hookedend 6 for being passed through a hole 6 in the end of the bar 1 to holdthe same, while the opposite end thereof can be passed through the holeor opening in the key D, as shown in Fig. 5. It

will be evident that in some cases the lug 1 A on the bar 1 can bedriven into the frame B, as where a keeper is not employed within theframe, such as is shown in Fig. 6, in which case the lock C and keeper Ecan be placed upon the face of the door and frame, respectively, so thatthe bar 1 can extend out from and between them.

It will thus be seen that my improved safety device for doors and lockscontains few parts, which are strong and durable when in use and are notliable to get out of order. They can easily and rapidly be stamped fromsheet metal by any suitable means in any desired manner. The device canbe rapidly and easily connected to and removed from a door and frame andwhen in use will be firmly and solidly set in position, so as to holdthe door securely in place and prevent the lockingbolt from beingtampered with or sawed, thereby rendering the same completelyburglar-proof at all times. The device can be used on any form of doorand at either side of the same without the addition of any parts to thedoor or frame.

What I claim as my invention, and desire to secure by Letters Patent, is

1. The combination with a door and frame, of a bar secured within andextending out from between said door and frame, a ratchetface on oneside of said bar, a clamping-plate fitting over and around said barthrough an opening in said plate, a tooth on said plate for en agingwith said ratchet-face to clamp said p ate against the door and jamb ofthe frame and hold said door in place within said frame, and a springcarried by said plate and engaging with the side of said bar oppositethe ratchet-face thereon to hold said tooth in engagement with saidratchet-face and to permit the releasing of the same.

2. The combination with a door and frame, a look, a bar secured withinand extending out from between said door and frame, said bar having anopening in its end, means on said bar for engaging with the same andwith said door and jamb of said frame to hold said door in place withinsaid frame, and a rod attached to the opening in said bar and to the keyof the lock for fastening said key.

In testimony whereof I, the said HARRY S. BRICKELL, have hereunto set myhand.
